SPECIFICATION forming part of Letters Patent No. 704,250, dated July 8, 1902. Application filed September 5, 1899. Serial No. 729,589- (No model.)

To all whom it may once axle a of the band-wheel, is provided with a Be it known that I, EDWIN A. HARDISON, a flanged neck 4. citizen of the United States, residing, at Santa 5 indicates a stationary cam, and 6 indi- Paula, in the county of Ventura and State of cates a cam-lever caught upon the flanged 5 California, have invented a new and useful neck st and upon the stationary cam 5 to slide Improvement in Tell-Rigs, of which the folthe tug-pulley on the shaft of the band-wheel lowing is a specification. to bring it into and out of engagement with My invention relates to an appliance for the friction-seat.

The tug-pulley loose extra tug-pulley into its seat, so that B, which is loosely mounted on the shaft or when the handle K is released the friction between the loose tug-pulley B and the cam-lever 6 will operate to return the lever 6 to its vertical position, thus to withdraw the loose tug-pulley from its seat. This construction allows the loose tug-pulley to be thrown out of gear when the load is upon it.

In practical operation when the tools have been withdrawn from the well the main bullrope L will be thrown off from the main wheel E. The handle K will be pulled to throw the lever 6 to throw the tug-pulley B into the friction-seat a. Then the handle J will be pulled forward to operate the knuckle H to draw the pulley g down to tighten the tugrope or extra bull-rope F. The force of gravity helps to keep the knuckle-joint bent and to hold the wheel g in place upon the extra bullrope or tug-rope F and to bend said rope to tighten it. Then the engine will be operated to turn the tug-wheelA,thus rotating the extra bull-wheel and one or both of the spools 1 2, thus to operate the rope for raising and lowering the sand-pump, and, when required, also for operating the rope for raising or lowering the casing. The sand-pu mp rope N is wound upon the spool 2, which is detachable from the extra bull-wheel shaft, so that it may remain stationary while the spool l is being turned to raise or lower the casing. The casing-rope will ordinarily be detached from the spool and will only be fastened to the spool when required to be used in raising or lowering the casing. The handle K, which operates the lever 6, is held by a suitable catch or ratchet, as at R, to hold the tug-pulley B firmly in its friction-seat a.

L indicates the band for the bull-wheel.

When the handle J is pushed forward, the knuckle'joint h is straightened, and thereby it lifts the wheel g from the extra bull-rope or tug-rope F to loosen the same.

Now, having described myinvention, what Iclaim as new, and desire to secure by Letters Patent of the United States, is

1. A well-rig, comprisinga band-wheel provided on one side with a beveled friction-seat; a loose tug-pulley mounted to slide on the axle of the band-wheel and beveled to fit the friction-seat of the band-wheel; means for sliding the loose tug-pulley into and out of the seat in the band-wheel; an extra bullwheel and shaft mounted on the side of the derrick opposite the main bull-wheel, said shaft being provided with two spools, one of which is fixed to the shaft and the other of which is journaled to rotate on the shaft; a latch or clutch for fixing the loose spool to the shaft; an extra bull-rope around the loose tug-pulley and the extra bull-wheel; and

means for tightening and loosening the extra slide the loose tugpulley on the shaft of the band-wheel to bring it into and out of en gagement with the friction seat; an extra bull-wheel; an extra bull-rope connecting said loose tug-pulley with the extra bull-wheel, and means for tightening and loosening said extra bull-rope.

3. The combination with the band-wheel, of the loose tug-pulley to rotate with the bandwheel; the extra bull-rope around the loose tug-pulley and the extra bull-wheel; a pivoted lever extending along the extra bull-rope and provided with a grooved wheel to run on top of the extra bull-rope, a knuckle-joint pivoted at one end to the lever and at the other end to astationarysupport; and ahandle pivoted to the joint of the knuckle for operating the knuckle-joint.

4. In a well-rig the combination with the band-wheel; of an extra bull-wheel provided with a fixed spool and a spool which is loose on the shaft and constructed to be coupled with and uncoupled from said shaft; and means for connecting and disconnecting the extra bull-wheel and band-wheel independently of the main bull-wheel.

5. Awell-rigcomprisingamainbull-wheel;

a band-wheel; a loose tug-pulley to rotate with the band-wheel; the extra bull-wheel; the extra bull-rope around the loose tug-pulley and the extra bull-wheel; a pivoted lever extending along the extra bull-rope and provided with a grooved wheel above the extra bull-rope to run thereon; a knuckle-joint pivoted at one end to the lever and extending downward therefrom and pivoted at the other end to a stationarysupport; and ahandle pivoted to the joint of the knuckle for operating the knuckle-joint to raise the grooved wheel when the joint is straightened, and vice versa. In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, at Los Angeles, California, this 26th day of August, 1899.
